Informational masking and the effects of differences in fundamental frequency and fundamental-frequency contour on phonetic integration in a formant ensemble

This study explored the effects on speech intelligibility of across-formant differences in fundamental frequency (ΔF0) and F0 contour. Sentence-length speech analogues were presented dichotically (left=F1+F3; right=F2), either alone or—because competition usually reveals grouping cues most clearly—accompanied in the left ear by a competitor for F2 (F2C) that listeners must reject to optimize recognition. F2C was created by inverting the F2 frequency contour. In experiment 1, all left-ear formants shared the same constant F0 and ΔF0F2 was 0 or ±4 semitones. In experiment 2, all left-ear formants shared the natural F0 contour and that for F2 was natural, constant, exaggerated, or inverted. Adding F2C lowered keyword scores, presumably because of informational masking. The results for experiment 1 were complicated by effects associated with the direction of ΔF0F2; this problem was avoided in experiment 2 because all four F0 contours had the same geometric mean frequency. When the target formants were presented alone, scores were relatively high and did not depend on the F0F2 contour. F2C impact was greater when F2 had a different F0 contour from the other formants. This effect was a direct consequence of the associated ΔF0; the F0F2 contour per se did not influence competitor impact.

Navigating equality:religious young women's perceptions of gender and sexuality equality

Equality has become an important concept within secular-liberal societies (Perrons 2005), with white, secular Western women interpellated as quintessentially embodying this equality (Gill and Scharff 2011; McRobbie 2011; Nayak and Kehily 2008). For religious organizations, the interacting spaces of gender and sexuality constitute two of the most contested terrains in rights-giving, and many religions are seen as less progressive regarding equality vis-à-vis other social institutions (Plummer 2003; Tosh and Keenan 2003; Weeks2007). Young religious women have to articulate how they fit into the contours of secular-liberal equality norms as religious subjects. This chapter will focus on how young religious women living in the UK made sense of equality in the context of their religion, focusing on attitudes to gender equality and sexuality equality.
